learn PARTS IN YOUR KITS need for arduino(part-4)

Pushbutons :- Momentary switches that close a circuit when pressed. They snap into bread-boards easily. These are good for detecting on/off signals.

Resistors :- Resist the flow of electrical energy in a circuit, changing the voltage and current as a result. Resistor values are measured in ohms (represented by the Greek omega character: Ω). The colored stripes on the sides of resistors indicate their value (see resistor color

code table).

Servo motor :- A type of geared motor that can only rotate 180 degrees. It is controlled by sending electrical pulses from your Arduino.These pulses tell the motor what position it should move to.

Temperature sensor :- Changes its voltage output depending on the temperature of the component. The outside legs connect to power and

ground. The voltage on the center pin changes as it gets warmer or cooler.

Tilt sensor :- A type of switch that will open or close depending on its orientation. Typically they are hollow cylinders with a metal ball inside that will make a connection across twoleads when tilted in the proper direction.

Transistor :- A three legged device that can operate as an electronic switch. Useful for control ling high current/high voltage components like motors. One pin connects to ground, another to the component being controlled, and the third connects to the Arduino. When the component receives voltage on the pin connected to an Arduino, it closes the circuit between the

ground and the other component.

USB Cable :- This allows you to connect your Arduino Uno to your personal computer for programming. It also provides power to the Arduino for most of the projects in the kit.
